SBO works with any type of softswitch. If you already have any softswitch then you can use it with SBO. However, SBO is directly integrated with SyncSwitch (softswitch) and therefore, it is not necessary to arrange any other softswitch. Since, SBO is directly integrated with SyncSwitch, it is a combined package we do not charge additional bill for it.
The SyncSwitch is an asterisk based carrier-grade softswitch that allows its users to run Calling Card, Call Shop, Call Back, PC to Phone, IP to IP, Mobile Dialer, Device to phone, On net calling and so on.
